Single-crystal graphene on Ir(110)

A single-crystal sheet of graphene is synthesized on the low-symmetry substrate Ir(110) by thermal decomposition C$_2$H$_4$ at 1500 K. Using scanning tunneling microscopy, low-energy electron diffraction, angle-resolved photoemission spectroscopy, and ab initio density functional theory structure electronic properties adsorbed its moir\'e with are uncovered. The layer forms a wave pattern nm length corresponding modulation properties. This demonstrated to enable templated adsorption aromatic molecules uniaxial growth organometallic wires. Not limited this, also versatile for 2D-layer makes it possible grow epitaxial layers ureconstructed Ir(110).
